Littionary, just make sure whenever you battle a set encounter (where you expect to find it, not roaming), before the battle, turn off Autosave and save right before, so you can battle the Pokémon again if necessary. If you don't catch it, so either all your Pokémon faint or the Legendary/Mythical faints, you can "X" out of ROBLOX and you can battle the Pokémon again.
